Why are liquidations based on the mark price?
The latest traded price is the price of the most recent trade for this contract. A large market order can cause a sudden price wick.
Using the latest price directly to determine liquidations helps prevent unreasonable liquidations caused by brief, abnormal price movements in a market.
For reference, the market shows: $BTC current price 80677.01 (24h +4.76%).
Don’t use borrowed money to trade with leverage—losses can happen faster than you expect.
